SPECIFICATION forming part of Letters Patent N o. 645,904, dated March20, 1900. Application filed December 6, 189;?. Serial No. 660,965 (Nomodel.)

The object of my invention is to provide a' superior cultivator forthoroughly outtin g, loosening, and pulverizin g the soil andfor-destroying weeds, and also to provide superior simplicity and easeof construction and operation.

The accompanying drawings illustrate my.

invention. v

Figure l is a perspective view of my newlyinvented cultivator restingupon the ground. Fig. 2 is a side elevation of the cultivator at work,dotted lines showingvthe device with the blades thrown out of theground. Fig. 3 is a frontelevation of the runner for the front end ofthe tongue. 1

, A indicates a cross-beam, on the under side of which and on oppositesides of the middle thereof are arranged cultivator-blades B, having,respectively, a front member b, fastened to the beam, with its width ina vertical plane, and a rear member b', extending obliquely behind thebeam and inclined upwardly from the front rearwardly. C indicates atongue connected with such cross-beam and provided at its front end withany suitable support or runner D to rest upon the ground. This may be awheel; but I prefer the form of runner shown, the same being a curvedfiat bar provided with a guiding or cutting edge orrib d, projectingfrom its under surface. The tongue is rigidly connected to the standardsC preferably at a distance from the ground, and the cross-beam ispreferably pivotally secured to the lower'ends of the standards, as bythe bolt or pivot c. The standards are preferablymade vertical, so thatthe Weight of the driver is placed directly over the crossbeam,preferably a triie nearer the front than the rear, so that in any changethat is to be made in the angle or position of the crossbeam there is nomore leverage to be overcome in moving it in one direction than in theother. A lever connection is preferably provided between the beam andthe tongue to hold the tongue at any desired angle with the beam.

E indicates a lever pivoted to the standards C by a pivot c.

a indicates a standard fastened to the beam A, and e indicates aconnecting-rod connecting the lever E with the cross-beam through themedium of the standard. The lever E is provided with a ratchet e. l

ct indicates a rack fastened to the standard Cl to hold the lever.

F indicates a draft .connection fastened to the beam and resting uponthe tongue. The tongue is practically held by the angle at the front ofthe draft connection, but is not fixed thereto. The doubletrees G arefastened to said draft connection. Y

The front lower corner of thecross-beam is rounded, as at 2, so thatwhen the machine is pulled forward it will run readily over the groundand over small obstructions.

In practical operation when it is desired to move the machine along theground without I-l indicates a seat fastened tothe top of the standardsC. y

The cutter d of the runner is intended to keep the runner from slidingtoo freely from` ,sideto side. The iiat portion of the runner keeps itfrom sinking into the ground.

The cross-beam is preferably made of two members 3 4, of oblongcross-section, and fastened together at an angle in cross-section togive great strength to the beam and considerable height to the front ofit.

It is to be seen that in practical operation when cultivating the tongueis rigid with the cross-beam and that the pivoted lever is simply forrelative adjustment.

Now, having described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. A cultivator comprising a cross-beam, provided with blades and havingits front por'- tion sled-shaped; a seat-standard pivotally secured tothe beam; a seat thereon; a short IOO standard secured to the beam; atongue and l and rear edges; a tongue rigidly connected a rack rigidlysecured to the seat-standard; with the seat-standard; means foradjusting a ratchet-lever connected with the short the position or angleof the beam relatively r 5 standard and pivotally secured to theseattothe standard above the pivotal point; a

5 standard; a support for the front end of the support for the front end0f the tongue; and tongue; and a draft connection secured to the draftconnections secured to the ends of the ends of the beam and resting uponthe tongue beam and resting upon the tongue above the above its support.support.

2. A eultivator comprising a sled-shaped ISAAC DENTON STOCKTON. 1ocross-beam provided with blades; a vertical Titnessesz seat-standardpivotally secured to the central JAMES R. TOWNSEND, portion of saidbeam, intermediate its front BRICE GRIMES.
